Sudoku Endless Puzzle
Read full descriptionHide full description
Sudoku Endless Puzzle is sudoku that never resets to a blank grid. You play the bottom three rows. Fill all 27 cells correctly and the band pops: the six rows above slide down, a freshly generated band drops in from the top, and the run continues. The board is always 9x9, always mid-game, always one band away from the next one. Every band is generated to be solvable by logic alone โ no guessing, ever. Early bands need nothing harder than a naked single; by level seven you are leaning on hidden singles, and pairs and locked candidates show up after that. The clue count is chosen two clears ahead, so difficulty rises with you instead of jumping. The first three bands are untimed. After that a band clock starts and tightens as you climb through five stages, from START to EVIL. Three mistakes also end the run. You score for every correct entry, plus a band bonus that grows with your level and multiplies for every consecutive band you clear without a mistake or a hint โ up to 3x. Clean play compounds; a single slip resets the streak. FEATURES - Endless falling-band sudoku, no level cap and no blank restarts - Every band logically solvable, verified before it ever reaches you - Difficulty that climbs with your level, chosen two clears in advance - Combo multiplier that rewards clean bands, up to 3x - A band clock from the fourth band on, tightening across five difficulty stages - Pencil notes, undo, erase, and hints you earn as you reach each new stage - Plays offline โ no account, no sign-in; only the ads need a connection - Your run is saved after every move, so you can stop mid-band and come back Free, with ads. A small banner sits along the bottom of the screen while you play, and a full-screen ad can appear between runs, never in the middle of one and never more than once every 90 seconds. Optional videos can win back a mistake when a run ends, earn a hint when you are out, add 60 seconds when the band clock runs out, or catch an extra lifebuoy. Optional in-app purchases: hint packs (10, 35 or 150 hints) and Remove Ads, which turns off the banner and the ads between runs. Reward videos stay available either way.
